I have read that brussels sprouts are one of those vegetables that not only survive the cold weather, but the flavor of brussels sprouts will improve with a light frost. Brussels sprouts are definitely a vegetable that gives cooler weather gardeners a boost for their gardening buck so to speak.
Brussels sprouts seeds are fairly small so make sure you plant them no
deeper than a quarter of an inch. While brussels sprouts may do well in
the cold, brussels sprouts seeds will need it to be a little warmer in
order to germinate. You can start brussels sprouts seeds indoors before
your last frost, but unless you have an extremely short growing season,
there really is no need since brussels sprouts will still grow in the
A slightly acidic soil (6.0 to 6.8 pH) works best for brussels sprouts.
First take a pH reading of your soil. It may be fine as is. If you
find that your soil is too alkaline (above 7.0), check out the article How to Lower Soil pH. In there you will find some excellent tips to adjust accordingly.
If you need to raise your soil’s level because it is too acidic, the
rule of thumb is to add lime or bone meal. For more information on
raising your soil’s pH level, check out How to Iprove Acidic Soil in Your Garden. There you will find more tips on your soil’s pH level.

In my experience growing brussels sprouts myself, and watching some
friends grow them, planting just a few brussels sprouts plants eighteen
inches apart in a square pattern will suffice. Think square foot
gardening when picturing what it looks like.
As a side note, just because you live in a warmer climate (Florida, the
gulf coast, etc.) does not mean you can not grow these tasty treats.
Direct sow brussels sprouts seeds into your garden from mid-October
Fertilize every few weeks with fish emulsion or compost tea to keep
feeding your brussels sprouts. Brussels sprouts are ready to be
harvested when the buds are firm. They will usually be the size of
large marbles (one inch).
A good companion plant for celery, cucumber and lettuce, one cup of
brussels sprouts contains 124% of the daily recommended amount for
